Re: [Tutor] I need advice about which way to go.
Hi Nathan, The problem with this problem descripton is that you have an idea clear in your own head but the rest oif us only have the words. So... I am writing a poker game and a blackjack game. Two separate games or one game that can play both? I was wondering which way would be Python smart and work properly. That depends on you really, there is no Python way to write card games (unless you count using PyGame but even thats not mandatory). This is really a matter of design and Python doesn't impose many limits on that, there are lots of valid approaches you could take. I am trying to figure out whether or not to use t(n) as a card indicator, when n = randomly drawn number. t(n) means a function called t that takes a parameter called n. I'm not sure how you would use that as a card indicator. Are you confusing functions and lists? Do you mean t[n] where n is an index into a list called t? Then if t held all the card values (or names) n could indicate one particular card. That might work. Another way could be a dictionary with a coded name per card as the key along with the value. (Aces pose a problem regardless of solution because they have two values) I could go that way, or code it as t1, t2, t3, etc. Having 52 variables, one per card could work but seems clumsy. Also figuring out how to deal a hand would be tricky with discreet variables. Which way is the right and correct way to go? There is no single right way, but a collection of some sort sounds better than a set of independant variables. Also for blackjack, I want to use it as playertotal = playertotal + n, and computertotal = computertotal + n. or 1,2,3, etc. Which is better? I don't understand that bit at all?! What does 'n'represent? What are the 1,2,3 for? Alan G. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] I need advice about which way to go.
Sorry about that, I thought it was clear that n = number randomly chosen. I was thinking of if the number was a five, it would choose a card with a five on it. I don't want to have to code stuff that I have to repeat again and again. I'm not worrying about card types, I have that figured out separately. The two games are indeed separate, too much trouble to do them a 1 program that can play both games. Maybe I should have shown my code and asked using the code as a visual reference. - Original Message - From: Alan G [EMAIL PROTECTED] To: Nathan Pinno [EMAIL PROTECTED]; Tutor mailing list tutor@python.org Sent: Wednesday, August 03, 2005 1:14 AM Subject: Re: [Tutor] I need advice about which way to go.

Now do you have an idea of what I'm pointing to?

Why not just use the random integer as an index? If you use range(13)
these if/elifs become
t1 =

if a == 1:
a =

playertotal = playertotal + 1

Same thing here.
What are the functions of b, t2, and playertotal? Especially for those of
us who don't know blackjack.
Does that help?

Re: [Tutor] I need advice about which way to go.
Playertotal is for calculating the total of the player's hand. This is
important, because if the player's total is greater than 21, he loses in
Blackjack. B is for the second card in the player's hand and t2 was for the
second card's type (i.e Heart, Diamond, Club, or Spade)

Re: [Tutor] I need advice about which way to go.
cards = {Ace, Two, Three, Four, Five, Six, Seven,
Eight,
Nine, Ten, Jack, Queen, King}
card_types = {Diamond, Heart, Spade, Club}
{} means they are dictionaries but you don;t provide key:value pairs.
You probably want lists here not dictionaries.
You can read about the differences in the Raw Materials topic of my
tutorial.
if t1 == 1:
t1 = card_types[0]
And you don't have a '0' key in your dictionaries so this will fail.
Now do you have an idea of what I'm pointing to?
I think we get the idea but you need to think about what exactly your
data looks like.
Why not break the program into bits, just write a small program that
draws cards,
or deals a small hand - two cards for blackjack! Once you have that
working just
get the basic rules sorted out so you can play the game. Then add the
money
bits once you have a working game.
This kind of evolutionary development is how most programmers build
up their code. Try sometjing oin the interpreter, turn it into a
simple
program that does one key thing right. Test it. Once it works go back
to the interpreter and try the next bit, write it into the program.
Test it and get it working. Check the oroiginal stuff still works too.
Repeat until done.
Its this interpreter/editor/test loop that makes Python such a
powerful
development tool.

Re: [Tutor] I need advice.
I want to write a program that will convert time in any other time zone to my time zone. This is a deceptively complex task. There are around 40 timezones varying by anything from 15 minutes to 2 hours. And some places change timezone throughout the year. Others have multiple daylight saving dates etc etc. Would it be better to use the Python time molecule Use the force Luke... If a standrad module exists then its almost certain that more thought and debugging has gone into it than you want to expend! Use what's there and tweak it to suit your needs.

Re: [Tutor] I need advice.
I forgot to tell that I use Python 2.2.3. When I first got Python, I got 2.4.1, but it refused to run the second time. So I went and got 2.2.3. Your answer would make sense if I had 2.4.1, but I don't. Version 2.3 should work and has the datetime stuff I think - just checked and it does... But 2.4 should work too, although I confess I haven't tried 2.4 yet except for cygwin. So it might be worth having another go at installing 2.4.
